Indeed....I was (unknowingly)thinking about the GE powered 767, which I have flown as opposed to the PW powered 767 which I fly now. On the PW powered 767 left AC bus failure leads to no autopilots...on the GE you still have the right hand one. A quick check of my QRH this morning resolved the ambiguity...one reason I don't make a HUGE effort to memorise things klike this.
Just one reason the GE 767 is a better machine.
